Cyclin E is a regulatory subunit of cdk-2 and controls G1/S transition during the mammalian cell cycle. Multiple isoforms of cyclin E are expressed only in tumors but not in the normal tissues, suggesting a post-transcriptional regulation of cyclin E. In vitro analysis indicated that these truncated variant isoforms of cyclin E are able to phosphorylate histone H1. Alterations in cyclin E protein have been implicated as indicators of worse prognosis in various cancers.
